Good work. I like the high-contrast. The top right is really successful at creating the illusion of leather. Lots of depth here, very sculptural. Do you have the photos you studied from? You've inspired me to do a few of these myself. I need work with cloth.

these are some really stylish jackets here,I really love your attention to detail on the many wrinkles,shading and lighting techniques and the many other things on each jacket,such as the buttons and zippers

It varies depending on what the item is. A basic coat with straightened sleeves might take 15 minutes or less, but one with more detailing in the design and a large quantity of wrinkles can easily take three times longer.
